Manu,
Thanks for picking this up on twiiter. The question was somewhat
inspired by not wanting to put both microdata and rdfa in a document.
And it also occurred to me that the RDFa 1.1 profile mechanism could
play role.
If there is a profile, it similarly defines the processing of itemtype
and itemprop. That's a small(?) extension of the model you describe.
But I like the separate document for defining how to interpret
microdata as RDFa. An '-i microdata' flag for RDFa parsers.
All in the spirit of "just throwing it out there".
